Description
Technical Field
The invention relates to an abrasive cloth, in particular to a flexible coating abrasive cloth.
Background
In the field of fine grinding of modern high-grade furniture, wooden artware, interior decoration, electronic products, automobile cosmetology and the like, dry grinding sheet type abrasive paper is the most common grinding product, has wide application range and convenient use, and is particularly suitable for fine processing of special-shaped surfaces such as edges, corners and the like of special grinding surfaces. In terms of the using method, the electric grinding tool can be applied, and the manual operation can also be directly used. The existing sheet sand paper base material is imported latex paper. The price is high, and the defects are obvious in practical application: poor mechanical properties, inability to withstand repeated stretching and folding; the use is inconvenient, the shape needs to be cut according to the contact surface of the tool or selected according to manual operation, and the effective utilization rate of the product is low; poor flexibility and easy damage, limits the application field, has low grinding efficiency, and has short service life due to poor anti-blocking function. The method is far not suitable for grinding fields with higher refinement requirements, such as electronic products, precision workpieces, automobile paint surface processing and the like.
For many years, people have sought to find a new substrate to replace paper substrates, but this is prohibitive for a number of reasons. The main reason is that the 300 mesh fine product requires a particularly flat substrate, which requires a high end adhesive to match the appropriate substrate. Aiming at the defects and market demands of the existing products, the invention provides the cloth-based flexible coating abrasive cloth, which replaces imported latex paper with the cloth base on the premise of not increasing the cost, effectively overcomes various defects of the existing paper-based products by developing a novel adhesive and combining with technological innovation of a preparation process, enlarges the application field of the products, greatly improves the grinding efficiency and anti-blocking effect of the products, prolongs the service life of the products, saves energy consumption and reduces the cost.
Disclosure of Invention
The invention aims to solve the technical problem that aiming at the defects in the prior art, the invention provides the flexible coating abrasive cloth which has good grinding efficiency, anti-blocking effect and service life, improves the efficiency, saves the energy consumption and reduces the cost.
The technical scheme for solving the technical problems is as follows:
a flexible coating abrasive cloth is prepared according to the following procedures: preparing a base material, singeing, alkali washing, water washing, high-temperature shaping, dipping, stretching, drying and shaping, sizing, sand planting, drying, glue compounding, drying, post-curing, kneading, detecting product performance, coiling and packaging, wherein:
(1) impregnation
Placing the base material in a dipping solution to be dipped for 10-15min at the temperature of 40-50 ℃, wherein:
the impregnation liquid comprises the following components in parts by weight:
adhesive: 30-40 parts of styrene-butadiene latex: 10-15 parts of a hardening agent: 1-2 parts of a softening agent: 0.5-1 part of penetrant: 1-3 parts of color paste black: 1-2 parts of water: 5-8 parts;
the adhesive comprises the following components in parts by weight:
phenolic resin: 40-50 parts of butyronitrile latex: 10-15 parts of surfactant: 3-5 parts of filler: 5-7 parts of a leveling agent: 1-3 parts of an antistatic agent: 1-2 parts of an anti-clogging agent: 0.5-1 part of coupling agent: 3-5 parts of a binding agent: 3-5 parts of a flame retardant: 1-2 parts of foaming agent: 1-2 parts;
(2) stretching, drying and shaping
Drying the base material by a setting machine, presetting at the temperature of 110-;
(3) electrostatic planting sand
The abrasive is bonded on the surface of the bottom glue of the base material through electrostatic sand planting, wherein:
when the abrasive is used, the abrasive is firstly treated, and the method specifically comprises the following steps:
the grinding materials are uniformly mixed to prepare grinding material micro powder, then a binding agent is added to the grinding material micro powder, and the grinding material micro powder is bonded, calcined and ground into polymeric grinding materials with different grain diameters for reuse.
The invention further defines the technical scheme as follows:
in the flexible coating abrasive cloth, the base material is purified fiber cloth.
The invention has the technical effect that the scheme of the invention replaces imported latex paper with purified fiber cloth. The cloth is made by processing fiber into yarn count and then weaving the yarn count in the warp and weft directions. Although latex paper is made of fiber, its mechanical properties such as tensile, bending resistance, pressure and rubbing resistance are far from comparable with those of cloth. This has been proven without prejudice by practice. The traditional abrasive cloth is mostly made of pure cotton cloth or chemical fiber cloth as a base material. Although the industrial cloth can be processed into thin products according to the requirements of users, the processing method is rough, and the flat cloth base product which is suitable for the requirement of the project is difficult to weave. It is known that the more finely ground abrasive cloth, the higher the requirements placed on the base cloth: ultra-thin, ultra-flat, ultra-soft, and have certain mechanical strength. The ultra-thin and ultra-soft chemical fiber cloth used by modern high-grade clothes has ultra-uniformity of yarn count and weaving compactness, which are the required base materials of the invention.
Aiming at the main defects of the existing flexible latex abrasive paper, the purified fiber cloth is innovatively used to replace the imported latex paper. By adopting a refined cloth treatment process, the super-soft toughness of the original similar product is greatly improved, the grinding performance and the use effect of the product are greatly improved, and the application range of the product is expanded; for example, when the product is cut, the product can be torn by hands, and the effect of neatly marking can be achieved, which cannot be achieved by any paper-based product.

The technical effects of further improving the adhesive force of the adhesive, improving the peeling strength of the product and achieving the purposes of difficult falling of sand grains and long service life
The invention has the beneficial effects that:
the abrasive used in the traditional product is generally of a single type, namely, the alumina is pure alumina, and the silicon carbide is pure silicon carbide. The abrasive of the invention is at least two of semi-brittle alumina, high-temperature calcined alumina and single crystal corundum, and is prepared into novel abrasive. The prepared product has the advantages of excellent grinding effect, long service life and high processing precision, and preliminarily realizes qualitative leap. The composite grinding material technology of the invention adopts a plurality of grinding materials to mix, fully exerts the excellent grinding performance of various grinding materials and overcomes the respective defects, greatly improves the grinding efficiency of products, has high processing precision, and can achieve the grinding and polishing integrated grinding effect of 600# fine products; the invention adopts polymeric abrasive, firstly prepares the abrasive micropowder, and then adopts novel ceramic bond or other high-bonding-strength and high-temperature-resistant bonding agents for bonding, calcining and grinding into the abrasive with different grain sizes. This abrasive, known by the name "polymeric abrasive", is characterized by:
1) the polymerized abrasive cloth has good self-sharpening performance. Because the polymerized abrasive belt is formed by bonding a plurality of abrasive particles with the same size together, the single abrasive direction in the abrasive particles is different, and new abrasive continuously appears in each layer in the grinding process, the grinding sustainability is realized;
2) the grinding is not easy to block. Because the periphery of a single abrasive has larger gaps, abrasive dust generated in the grinding process can be taken away in time so as to reduce the residue on the surface of the abrasive belt;
3) the service life of the abrasive cloth product is long. The common abrasive belt is single-layer sand planting, and the quantity of the abrasive materials in unit area is limited; the effective abrasive amount on the abrasive cloth using the polymerized granulation abrasive can be greatly improved; meanwhile, due to the fact that the grinding material has a three-dimensional structure, the utilization rate of the grinding material is greatly improved.
4) The grinding and polishing quality is stable. The traditional abrasive belt is a single-layer abrasive particle, and the grinding efficiency is obviously inconsistent when the abrasive belt is in an initial state, a middle state and a final state, so that the surface quality of a workpiece is often greatly different, and the high Ra value generally represents that the early stage is high and the later stage is low; but the grinding capacity of the flexible polymerized abrasive belt before and after grinding is relatively stable, the impact force on a workpiece is small, the Ra value is relatively stable, and the consistency of the surface grains of the product is good.
5) The new product has a strong adaptability to automated grinding tools. In high-end manufacturing of mechanical products, the automation level is continuously improved, the application of a numerical control grinding machine is the most, the abrasive belt is frequently replaced, labor and time are wasted, the advantages of the numerical control grinding machine cannot be played due to the defects of quality, efficiency, service life and the like of a traditional single-layer abrasive belt in the using process, the soft abrasive belt is completely qualified for the use of the numerical control grinding machine, the labor intensity of operators is reduced, the efficiency is improved, and the energy consumption is reduced.
In conclusion, the abrasive belt with the accumulated abrasive has high grinding efficiency, large space for containing chips of the abrasive particles, difficulty in blocking, good self-sharpening property of the abrasive particles, low temperature rise during grinding, ultra-long service life, good and stable grinding surface quality and suitability for the use of automatic equipment.
The adhesive is a key material of the core technology of the product. The product belongs to fine grinding abrasive cloth, and is characterized by super flexibility. The product therefore places high demands on the use of adhesives: the bonding strength is high, even the 800# abrasive particles with fine size can be firmly bonded without falling off; strong elasticity, which is a necessary condition for product flexibility, easy folding, no chapping, hand-tearable, abrasion-resistant, etc., absolutely not feasible without high elastic characteristics; the leveling property of the adhesive is good, the base material after treatment is light and thin, and the good leveling property of the adhesive is an essential property in both head gluing and glue compounding processes, so that the leveling property and the texture uniformity of a product can be ensured, and the effect of precise grinding of the product can be ensured. In order to enable the adhesive to have good bonding strength and higher elasticity and leveling property, the phenolic resin doped polyurethane and the epoxy resin material are used for modifying the adhesive, and the prepared special adhesive has high bonding strength and strong flexibility and elasticity, thereby ensuring the comprehensive efficiency of a new product, prolonging the service life of the product and improving the cost performance of the product; the filler of the adhesive adopts molybdenum disulfide, graphite and talcum powder as fillers, the graphite material is easy to slide due to the specific crystal structure, and meanwhile, the graphite dry friction lubricant has adsorbability, can form a layer of lubricating film (graphite crystal film) to play a role in reducing friction and wear, has good heat dissipation and heat conductivity, and cannot generate the phenomenon of seizing welding of carbon and metal materials due to the high melting point of the carbon; the talcum powder is used as a filler, can play a role of a framework, reduces the manufacturing cost, simultaneously improves the hardness of the adhesive, increases the stability of the shape of a product, increases the tensile strength, the shearing strength, the bending strength and the pressure strength, reduces the deformation, the elongation, the thermal expansion coefficient, the whiteness, the uniform granularity and the strong dispersibility and the like, and optimizes the ductility, the processability and the like of the adhesive; the graphite and the molybdenum disulfide are mixed together for use, the graphite and the molybdenum disulfide have good synergistic effect, and the graphite and the molybdenum disulfide are mixed for use according to a certain proportion, so that the wear resistance of the adhesive can be effectively improved, and the loss in abrasion and the friction coefficient are reduced.
The invention adds some antistatic and anti-blocking materials into the adhesive to carry out coating treatment before sand planting, thereby achieving the effect of non-adhesion (anti-blocking) of abrasive dust during grinding.
The adhesive has the following functions of ① excellent elasticity, so that under the action of grinding pressure, corresponding elastic deformation can be generated, the abrasive belt is promoted to form completely-jointed microcosmic contact with the surface of a workpiece, corresponding 'expansion' can be generated by abrasive particles, scratches on the surface of the workpiece are reduced, ② good chip removal performance and proper sand removal rate are achieved, ③ is high in hardness and strength, and the adhesive has strong sharpness during working.
The invention strictly controls the time and temperature of the dipping to achieve the optimal state, therefore, the process directly influences the subsequent stretching and shaping until the uniformity of gluing, the uniformity of sand planting and the balanced quality of the end product. Because the dipping process is not well treated, the phenomena that the adhesive is easy to peel off, the quality of the edges and the quality of the middle of the two edges are not uniform, the flatness is not uniform and the like can occur after the product is taken off line, the components of the dipping solution are controlled during dipping, wherein 'latex + hardener' is selected, and the problems of moderate mechanical strength and poor peeling strength are solved;
1. aiming at the main defects of the existing flexible latex abrasive paper, the purified fiber cloth is innovatively used to replace the imported latex paper. By adopting a refined cloth treatment process, the super-soft toughness of the original similar product is greatly improved, the grinding performance and the use effect of the product are greatly improved, and the application range of the product is expanded; for example, when the product is cut, the product can be torn by hands to achieve the effect of neatly marking, which cannot be achieved by the existing paper-based products.
2. The special adhesive prepared by modifying the adhesive by using the phenolic resin doped polyurethane and the epoxy resin material has high bonding strength, high flexibility and elasticity, ensures the comprehensive efficiency of a new product, prolongs the service life of the product and improves the cost performance of the product.
The base material used in the invention replaces imported latex paper, so that the cost is saved, the flexibility is improved, and the invention also has the main advantages of convenient use: the required size can be torn at will in both warp and weft directions, and no material waste is caused. This is not possible with "paper" type substrates. Because of the flexibility, the product application field is enlarged, and the grinding efficiency of the product is greatly improved.
